The right tools for the job: towards preference and performance considerations in the design of virtual reality interactions

Virtual reality (VR) users interact with virtual objects using motion-tracked controllers. While many devices utilise abstract button pushes for interactions, some allow for limited finger tracking by estimating finger positions based on sensors. In this study, the Vive Wands and the Valve Index controllers were compared in three tasks: direct interaction with objects (throwing), tool usage (bow) and indirect control of a character (remote-control). Forty-four participants completed each task with both devices and rated the usability of the device after each task. Results showed only differences in preference for the remote-control task. Some participants noted that using the thumbstick of the Index instead of the touchpad of the Wands controller felt more natural in this task. However, performance did not differ between devices in any task. Therefore, future research should not only compare designs of controllers but also consider assets and interactions, as there may be preference and performance differences for certain combinations.
